An EM algorithm for estimating the parameters of the multivariate skew-normal distribution with censored responses
ArticleAbstract: Limited or censored data are collected in many studies. This occurs for many reasons in several pracPalabras claves:Censored dataa, EM algorithm, Extended skew-normal distribution, Truncated distributionsAutores:Christian Galarza Morales, Lachos V.H., Matos L.A.Fuentes:googlescopusFinite mixture modeling of censored and missing data using the multivariate skew-normal distribution
